This is Roman's idea, but he is busy gearing up for the new hockey season.

The idea is to have a vest for a coach which gives their coaching a sound boost. They have a small group, but usually in a noisy spot. They would like their voice to be heard by everyone. It could be good for soccer, football, or rugby coaches and even perhaps outdoor yoga classes as well as hockey.

Roman would like it to be light weight and washable. Does this seem useful? What features would you like to see?

Hi,It is on the cards, but we would appreciate some help. What features would you like? Does it have to be all washable, or would you be happy to remove bits from the pocket to put the fabric through a wash? What sport are you mostly interested in?
